终传动为行星齿轮系统,可增加和传输车轮扭矩。 链 ( 17) 将终传动链轮 (7) 连接至各车轮心轴 (19) 上的车轮链轮 (15),并驱动每个车轮。 终传动也是各个串联轮子摆动的枢轴。

差速器驱动太阳齿轮和轴 (1)。 太阳齿轮 (1) 驱动行星齿轮 (13)。 行星齿轮 (13) 在齿圈 (3) 内转动。 行星齿轮 (13) 驱动托架 (2)。 托架 (2) 通过花键固定在输出轴 (8) 上。

两只链轮 (7) 通过花键固定在终传动的各输出轴 (8) 上。 链轮 (7) 位于车轮间串联驱动的中心位置。 位于中心位置和链轮 (15) 之间的链 (17) 驱动串联驱动上的车轮。 车轮心轴 (19) 通过花键固定在车轮链轮 (15) 上。 车轮链轮 (15) 转动车轮心轴 (19)。

串联壳体 (16) 通过螺栓与枢轴壳体 (11) 连接。 枢轴壳体 (11) 使车轮能够摆动壳体 (16)。 两个耐磨环 ( 10)、垫圈 ( 5) 和两个密封件 ( 4) 位于终传动壳体 (12) 和枢轴壳体 (11) 之间。

车轮心轴壳体 (18) 也包含行车制动器部件。 串联壳体中的机油可润滑和冷却制动器部件。 此机油可通过车轮的转动进行循环。

液压油添加剂

本机器上的行车制动器设计为利用含有液压油添加剂的纵列传动箱油来工作。 这种添加剂可以减少制动器噪声和制动抖振。

参考: 请参考操作和保养手册, "加注容量"或操作和保养手册, "润滑剂粘度"以了解关于加装 液压油添加剂的更多信息。
